What is Solvent Extraction and Why is it Important?

The simplest solvent extraction examples may be derived from water and organic compounds. For example Benzene is non polar and is immiscible in water as the polarity of water is very high. So, if we want to separate benzene from a liquid which contains a component that dissolves in water, then we can mix it with water and the separated layer will be benzene.
